EventSource
The EventSource class provides methods for monitoring signals.

This module exposes no properties.

Method
Description
select
select(property: string): EventSource
Converts event source by selecting a property in the event object. Events without specified property are ignored.
skip
skip(count: number): EventSource
Yields a filtered event source: the first count events from the original source are dropped, and subsequent ones signaled.
subscribe
subscribe(callback: (event: mixed) => void): Subscription
Sets a callback for the event source. The callback will be invoked every time an event is emitted from this EventSource.
See Also: Subscription.unsubscribe.
Note: subscribe and subscribeOnNext functions are completely equivalent.
subscribeOnNext
subscribeOnNext(callback: (event: mixed) => void): Subscription
Sets a callback for the event source. The callback will be invoked every time an event is emitted from this EventSource.
See Also: Subscription.unsubscribe.
Note: subscribe and subscribeOnNext functions are completely equivalent.
subscribeWithSnapshot
subscribeWithSnapshot(snapshot: { [name: string]: Signal}, callback: (event: mixed, snapshot: mixed) => void): Subscription
Sets a callback for the event source, similar to Subscribe function, but with additional Snapshot parameter. Snapshot is a dictionary of String/Bool/Scalar signals, which will be passed as JSON to the callback function using lastValue from requested signals
take
take(count: number): EventSource
Yields a filtered event source: the first count events from the original source are signaled, and subsequent ones ignored.
